Title: Scroll compressor
Inventor: TAGO MASATO
IPC: F01C1/02
Filed: 1982-03-31
Abstract: PURPOSE:To prevent the seizure at the sliding surfaces between scroll vanes of a scroll compressor, by forming a lubricating oil collecting groove in the surface of a shroud, and opening an oil supply passage at the bottom of the oil collecting groove in the manner that the oil supply passage is communicated with the end face of a fixed scroll vane. CONSTITUTION:An oil collecting groove 33 for collecting lubricating oil temporarily is formed in the upper surface of a shroud 21. This oil collecting groove 33 is an annular recess formed concentrically around a discharge port 24, and an annular land 34 is formed between the discharge port 24 and the oil collecting groove 33. Further, an oil supply passage 35 is formed at the deepest bottom of the oil collecting groove 33. Here, since the oil supply passage 35 is extended through the inside of a fixed scroll vane 23 in the axial direction and opened in the end face of the vane 23, it is enabled to prevent seizure of the sliding surfaces between the scroll vanes of a scroll compressor.

Title: Interphone device
Inventor: INUI KENICHI
IPC: H04M9/00
Filed: 1983-03-30
Abstract: PURPOSE:To prevent an indoor talking from being disturbed by individual calling by adopting 2-wire nonpolarity system for wirings, superposing a transmission signal on a power supply line from a master station and corresponding the supplied power potential from the master set and the operating state in response to the operating state. CONSTITUTION:The 2-wire nonpolarity system using a line 7 is adopted between indoor sets and indoor sets, e.g., door phones 4, 5 are connected individually to a master set 1 via a line 8 or 9. The master set 1 identifies the door phone 4 by a call signal from the door phone 4 caused by the short-circuit between the two wires of the door phone line 8 (t1) and transmits a call tone to the indoor line 7 and a back tone to the door phone line 8 (t2). In hooking up a handset of the master station 1 and any of sub- master sets 2, 3 in response to the call from the door phone 4, the master set 1 detects the hooking-up of the handset, brings an indoor line voltage to a VCC1 and also connects the door phone line 8 and the indoor line 7 so as to attain the talking between the door phone 4 and the indoor set (t3). When talking between the door phone 4 and the indoor set is finished and the handset is restored, the master set 1 brings the voltage to an indoor line voltage VCC0, and disconnects the indoor line 7 from the door phone line 8 and restores the mode to the original standby state.

Title: Optical information recording and reproducing device
Inventor: KUDO TAKASHI
IPC: G11B7/125
Filed: 1997-03-07
Abstract: PROBLEM TO BE SOLVED: To provide compatibility that enables reproduction under the same conditions concerning the optical information recording medium of a CD-RW system as that of other than the CD-RW system by a three step gain switch, in the structure of an optical information recording and reproducing device that deals with the optical information recording medium of the CD-RW system. SOLUTION: A laser power at the time of reproduction of a laser beam source is set differently between the optical information recording medium of CD-RW system with a greatly different reflectivity and that of other than CD-RW system; as a result, a reproducing reflected light quantity from either optical information recording mediums is nearly equalized, so that the gain of a current-voltage conversion amplifier 1 at the time of reproduction can be made common for either mediums; after that, a gain for recording time is only differentiated between the optical information recording medium of CD-RW system and that of other than CD-RW system, enabling all to be dealt with by a three step gain switch.

Filed: 1996-03-11
Abstract: PROBLEM TO BE SOLVED: To eliminate the need of a troublesome operation for a user by automatically setting heater output at a low level after recovery from a power failure, upon the occurrence of the power failure during an operation. SOLUTION: When an operation is stopped due to a power failure, a power failure end detection means detects the status of the end of the operation, and the status is stored in a non-volatile memory means. At the next operation, the previous operation is identified as stopped due to a power failure, on the basis of the memory status (S1), thereby lowering the standard setting of heater output at a low level (step S11).

Filed: 1988-03-07
Abstract: PURPOSE:To reduce the cost of device and simplify a structure thereof by a method wherein an electric dust collector is arranged in an air flow passage of a fan heater. CONSTITUTION:When a fan 3 is operated, air at first passes through an electric dust collector device 5 and the air is cleaned. After this operation, the air passes through a combustion device 7 within a fan heater 1 and exits out of a hot air outlet port 2. Some of dusts 8 are not adhered to a dust collecting pole 5-1 while they pass through a clearance between dust collecting poles 5-1, so that the air is not necessarily cleaned at the electric dust collector 5. However, the air passes through a combustion device 7 at a next stage, so that the remaining dust 8 is ignited there. With this arrangement, since a purification by the electric dust collector device 5 and a purification by the combustion device 7 are performed in duplicate arrangement and a degree of purification is improved.

Abstract: PURPOSE:To prevent lowering of availability factor by opening a part of load upon exceeding of the temperature of a reactor and a main transformer over such level as corresponding to the upper limit of overload withstandability, thereby preventing useless opening of the load. CONSTITUTION:DC current collected from a stringing through a current collector 1 is fed through a circuit breaker 2, a filter reactor 3 and a filter capacitor 4 to a converter 5 where it is converted into AC current and fed through a main transformer 6 to loads 7, 8. Temperature of the main transformer 6 is detected through a temperature sensor 9 and compared with a value set in a reference temperature setter 10 through a comparator 11. When it exceeds over the value set in the reference temperature setter 10, a load release contactor 13 is turned ON through an amplifier 12 to release the load 8 through main contact. On the other hand, reference temperature to be set through the reference temperature setter 10 is lowered through an auxiliary contact 13, thus providing hysteresis characteristic.

Abstract: PURPOSE:To demodulate exactly a recording data even when a reproducing pulse is opposite in phase by recording an information signal for detecting a phase first, when recording a data in an external recording medium, and demodulating the data in accordance with its phase direction, when calling the data from the recording medium. CONSTITUTION:In case of loading, namely, reproducing a tone color data to a RAM 4 from a cassette tape recorder CMT 11, a loading SW is turned on, a CPU 2 starts the CMT and an MT 12 is read out. When an expression (T1-T2)>(T3-T4) is formed by values T1-T4 in a register, the CPU 2 decides that a data pulse which has been sent from the MT 12 is not inverted, and sends the same phase signal A to a phase detecting means 13. The phase detecting means 13 which has received the same phase signal A commands a rise width measuring demodulation mode B, and a demodulating means 14 executes a demodulation processing of a data by a rise edge. When it is decided that the expression is not formed, the phase detecting means 13 commands a fall width measuring demodulation mode B to the demodulating means 14, and the demodulating means 14 executes a demodulation processing of the data by a fall edge.
